Explore how endothelial damage, atherosclerotic plaque and plaque-triggered thrombosis restrict coronary blood flow and can cause myocardial infarction in IB Biology SL B3.2.6.
Outline the causes and consequences of blood clot formation in coronary arteries.
| a | coronary heart disease/CHD/coronary artery disease/CAD occurs when there is reduction of oxygen to the heart muscle; |
| b | high ratio of LDL to HDL/fatty diet leads to plaque formation in arteries; |
| c | plaque breaks off causing damage that activates blood clot formation; |
| d | clots in the bloodstream may block a coronary artery/coronary thrombosis reducing blood flow/oxygen OR clots can cause heart attack/muscle death; |
| e | sickle cell anemia crisis produces blood clots that can cause coronary/arterial blockage; |
